CHARLES E. MOMANUS, OF NEW YORK, N. Y.

MACHINE FOR CUTTING DISKS.

To all whom it may concern:

Be itknown that I, CHARLES E. Mo- MANUS, a citizen of the United States,residing at No. 25 Fort Washington avenue, borough of Manhattan, city,county, and State of New York, have' invented certain new and usefulImprovements in Machines for Cutting Disks, of which the following is aspecification, reference being had therein to the accompanying drawings.My invention relates to improvements in slicing machines andparticularly those for cutting disks from cylindrical rods of cork. Theobject of my invention is to provide certain details of construction fordiskcutting machines of the rotary magazine type to prevent the-cuttingof imperfect disks.

In the accompanying drawings a Figure 1 is a plan view showing rotarytable and knives.

Fig. 2 is a perspectlve of feeding and centering devices. I

Fig. 3 is a front view of feeding device shown in Fig. 2.

Fig. 4. is a cross-section on line 44 of Fig. 5 is a bottom plan view,with knife removed, of Fig. 4.

Fig. 6 is a sectional view on line 6-6 of Fig. 7 is a detail view of oneof the centering jaws. 4

Fig. 8'is a bottom plan view, partly section, of a modification of thegripping devlce. Figs. 9 and 10 are details of another modification ofthe gripping device. I

Fig. 11 is a vertical section of one of the feeding tubes showingadditional centering device.

Fig. 12 is a sectional view of another modification of gripping deviceon line 12- 12 of Fig. 13.

Fig. 13 is a sectional view on hne 1313 of Fig. 12. p

The rotary table, A, is provided with a plurality of apertures A adacent to its periphery in which are fitted tubes B as supports 'for thecork rods. The' rotary knives, O, are provided with w1pers, 0.

' The following is a description of the feeding device. A pair of:grippers or corrugated disks, D D', are mounted on shaft (2, insupports, e, secured to the table, A. The disk D is fixedly secured tothe shaft while the disk D is loosely mounted thereon by Specificationof Letters l'atent. Patented Mar. 19, 1918. Application filed September25, 1914. Serial No. 863,486. I

rod is continuously gripped by the disks,

and thatrods of different diameters will be gripped by them. A ratchetwheel, H,.is secured to the outer end of shaft, d, and is operated bypawl, J pivoted to supports, K K, loosely mounted on the shaft on eitherside of the-ratchet wheel. As the table revolves the pawl is thrown intoengagement with the ratchet by trips, L, the disks are moved through theproperarc and the rod forced downward the required distance.

In the cutting of disks from rods it is important. that the disks be ofuniform thickness. If the rod turns as it will under the action of theknife unless means are provided to prevent, a wedge-shaped. diskresults. To prevent the turning mentioned I against the ribs which holdit against turn-' ing. The modification shown in Figs. 12 and 13embraces ring W, but havingribs only on a portion of its innercircumference as shown, and spring Y which presses the rod against theribs. In the device shown in Figs. 12 and 13. the last end of the rod isheld for cutting so that the final remnant if anv is les than therequired thickness of the disks being cut and not greater, thus avoidingthe necessity of sorting out thick disks. The modificationshown in Fig.8 consists of pivoted arm S, carrying loosely mounted corrugated sleeve8, which. latter is kept in contact with the rod by means of spring t.If the ribs are toothed like a saw thev take a firmer grip.

The centering device (shown in Figs. 4 and 5) is designed to permit thecutting of rods of different diameters in the same tube.

Toothed rings. M M. provided with oblique slots. m, are fitted in thetable around the aperture A and above and below bushing P are forcedinward or outward by the action of the oblique slots on the pins of thejaws. Thu a rod smaller than the tube can be held in proper position forcutting. The jaws are provided with vertical corrugations to hold therod against turning by the action of the knife.

It is also found that, if the rod tilts as is quite likely when rodssmaller than the tube are being cut, wedge-shaped disks are pro duced.To overcome this I employ the device shown in Fig. 11, consisting of thehinged eccentric R arranged to operate through slot r in the tubes andadjusted by means of set screw a: so as to hold the rod the requireddistance away from the side of the tube. This device is located oppositethe feeding disks which in action force the rod away. Thus the rod isretained in center as it is practically supported at four points, two bythe disks themselves, one by their forcing action, and one by theeccentric R.

I claim:

1. In a machine for cutting slices from rods, 2. pair of rotatable disksarranged in planes tangential to the rod and adapted to grip the rodbetween their faces and ad- Vance the sr ne when rotated.

2. In a machine for cutting slice from rods, a pair of disks mounted ona shaft tangentially to the corresponding rod, one of said disks fixedlymounted on said shaft, the other loosely mounted thereon so as to permitof a lateral motion but rotating with the shaft, means for pressins thesame toward the fixed disk so as to grip the rod, and means for rotatingsaid shaft.

3. In a machine for cutting slices from rods, a pair of disks rotatablymounted in substantially narallel perpendicular planes tangentially tothe corresponding rod and adapted to grip the rod between their innerfaces, means for maintaining a gripping pressure on at least one of saiddisks, and means for rotating said disks through a predetermined arc.
